GRAIN- SPECIFICATION forming part of Letters Patent No. 808,090, dated November 18, 1884.

Application filed March 14, 1884.- (No model.)

To all whom it may concern:

Be it known that we, WINFIELD W. MUL- LEN and FRANCIS M. MULLEN, of the town of Bunker Hill, county of Miami, and State of Indiana, have invented certain new and useful Improvements in Grain-Drills, of which the following isa specification.

Our said invention consists in improvements in the construction of graindrills, whereby the feeding mechanism is much simplified, and all the advantages resulting from simplicity secured, as will be hereinafter more particularly described.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1' is a top or plan view of agraindrill embodying our said invention; Fig. 2, a side elevation of the same; Fig. 3, a rear elevation; Fig. 4, a transverse vertical sectional view looking to the right from the dotted line 2 2; Fig. 5, a transverse vertical sectional view looking to the right from the dottedline 1 y,- Fig. 6, a central longitudinal section on the dotted line 00 0c, and Fig. 7 a detail perspective view showing the construction of the feed-wheel more plainly.

In said drawings, the portions marked A represent the frame-work of the machine; B, the seed-box; O, a feed-shaft; D, the main supporting and driving wheel; E, spouts for conducting the grain from the seed-box to the hollow teeth, and F said hollow teeth.

The frame-work A is or may be of any suitable construction, and is provided with the usual handles and means for attaching power to draw the machine.

The seed-box B is of the appropriate size, and is supported on the uprights A between the handles, the brackets a extending outfrom said uprights under said box. The bottom of said box is made to slope from each end toward the middle, and at the middle it is provided with an opening, b,which extends crosswise thereof. A small box, B, is constructed under this opening, in which the end of the feed-shaft operates, and to the under side of which the spouts for conveying the seed to the teeth are secured. A cut-off, B is mounted 50 on the under side of the box B, and adapted to be slid back and forth by the lever b between said box B and the box B, and thus govern the flow of the seed. Asuitable cover,

B is provided for the box, it preferably being adapted to slide in grooves in the sides, as shown.

The feed-shaft G is journaled at its front end in a bearing, 0, on the frame, and at its rear end in suitable bearings, o in the front and rear ends of the small box B under thebox B. The rear end of this shaft is provided with a feed-wheel, G, to feed the seed from the box in which it operates into the tubes which conduct it to the teeth. This wheel is divided by rings 0, which are so located as to separate the entrance to the tubes each from the other, and thus keep the seed feeding into each tube independently of the others. It is loosely mounted on the shaft 0, and held from turning independently by the spline 0 which also permits the shaft to he slid endwise with out moving said feed-wheel. It is driven from the main or driving wheel D by the miter gear-wheel 0 upon its ends meshing with the miter gear-wheel don the shaft of the wheel D.

A forked lever, O, is pivoted to the front side of the box, which engages with the collar c on the shaft, and is adapted to slide said shaft back through the feed-wheel until the gear-wheels are disengaged,when desired.

The supporting and driving wheel D is of the usual construction, and is mounted on the shaft (1 in the frame in the usual manner. It has a miter gear-wheel, (1, formed near its center, which engages with the wheel 0 upon 8 5 the shaft 0, as before described. This may be a separate wheel mounted on the shaft beside the wheel D, if preferred.

The spouts E are of any desired size or material. They are all connected with the box 0 B, in line with each other, and directly under the opening in the bottom of the box B. Each one is then run to its tooth and crooked so as to bring the ear 6 against the beam F, where it is secured by the bolt 6, as shown, and the 5 tube is thus held steadily in place.

The teeth F are hollow or bent into cylindrical shape, and have share-points, as is usual. They are pivoted at their rear parts to the beams F, on the bolts f, and have open tops, roo

into which the tubes discharge, as before described. By forming a series of holes in the rear part of the tooth as shownfit can be pivoted at any height desired on the beam. Said beams F are rigidly secured to the framework, and extend back to the proper places for the teeth, the rear part being turned down to form a vertical portion to which the teeth can be pivoted, as described.

Our invention operates as follows: The parts being in operative position as shown, the seed is put into the box and the machine set in operation. The cut-off being slid back,the seed falls into the opening in the bottom of the box. As the rings upon the feed wheel 0 fill the opening at the top, the seed is fed separately into the several tubes, as before described. When it is desired to stop the flow of the seed, the cutoff is again slid into position, and the opening is thus closed and the seed prevented from falling into the lower box, B, until the cut-ofl' is again drawn back. Then it is desired to stop the operation of the feeding mechanism, the shaft C is drawn back by means of the lever 0 and the gear-wheels thus thrown out of engagement with each other.

Having thus fully described our said invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a grain -drill, the combination of the driving-wheel, a single shaft running directly therefrom to beneath the seed -box, a feedwheel mounted directly upon the end of said shaft, said seed-box, the bottom of which is inclined from each end toward a transverse opening in the bottom, and a series of tubes connected to said box directly under said opening in line with each other and with said feedwheel and shaft, substantially as shown and described, and for the purposes specified.

2. In a grain drill, the combination of the frame-work, the main driving-wheel, the seedbox, a shaft running directly from said driving-wheel to beneath said seed-box, and a feedwheel mounted directly upon said shaft and revolving therewith, substantially as shown and described.

3. The combination, in a grain-drill, of the frame A, seed box B, feedshaft 0, one end having a feed-wheel mounted thereon, and being mounted in the box B under the opening in the boxv B, the tubes E, secured to the under side of said box B in line with each other, said feedwheel having rings thereon which separate the entrances into the several tubes, and the teeth F, all substantially as described, and for the purposes specified.

4. In a grain-drill, the combination of the frame A,seed-box B,having atransverse opening at its lowest point, and a box, B, secured thereto under said opening, the shaft G,having a feed -wheel, G,*on one end, said feed wheel being mounted in said box B, the drivingwheelD, andspouts E,leading from thefeed-box to the teeth F, said teeth F adj ustably pivoted to the beams F, all substantially as described, and for the purposes specified.

5. The combination, with a grain-drill, of a feed-box the bottom of which slopes toward an opening therein, a small box, B, secured under said opening, and a feed-wheel mounted in said box B, having rings around it at suitable intervals as ameans for providing an independent feed for each of the tubes below, substantially as set forth.

In witness whereof we have hereunto set our hands and seals, at Bunker Hill, Indiana, this 10th day of March, A. D. 1884.
